Juvenile plantar dermatosis is a localized desquamative scaling and fissuring dermatitis of the plantar surface seen in children, most commonly between the ages of 8 and 13 years. The condition is more frequently encountered in atopic children (with one study showing atopy in approximately 80% of affected children).
Juvenile plantar dermatosis is thought to be caused by repeated maceration followed by drying, inducing impairment of the superficial epidermis. Flares are episodic and last 1-2 weeks. Additionally, contact dermatitis has been reported in many of these patients (41% of patients with juvenile plantar dermatosis in one cohort).

Differential Diagnosis & Pitfalls
- Tinea pedis – May present similarly but can be easily differentiated by demonstrating fungal elements using a potassium hydroxide (KOH) preparation from scale or sending a swab for fungal culture.
- Dyshidrotic dermatitis – Presents with fissuring of the digits and plantar margins.
- Allergic contact dermatitis – Involvement of the dorsal versus the plantar surface of the foot is dependent on the specific component causing the allergy. Shoes, socks (dye, elastic), personal care products, shoe deodorizers, antifungal preparations, and detergents may be implicated.
- Psoriasis – Can also affect the bilateral soles. Additional pertinent skin and nail findings can help make this diagnosis.
- Pitted keratolysis – Distinguished by atrophic pits; organism can be demonstrated by culture.
- Keratoderma – Often involves the palms as well, and patients may report a family history of similar findings. This may be acquired or congenital, the latter associated with other features on clinical examination.
